Project description:Primary pulmonary artery sarcoma is a rare tumor that is highly fatal. It can be misdiagnosed as acute or chronic pulmonary thromboembolic disease. Herein, we report the case of a 22-year-old woman with a preoperative diagnosis of pulmonary embolism and superior vena caval thrombosis. Intraoperatively, an extensive sarcoma was seen to extend retrograde from the pulmonary artery, past the right ventricle and right atrium, and into the superior vena cava. Surgical resection of the tumor and reconstruction of the central pulmonary arteries, followed by adjuvant chemotherapy, relieved the clinical symptoms. The patient remained free of cancer at 14 months postoperatively. We believe that this is the 1st report of a primary pulmonary artery sarcoma that extended retrograde into the superior vena cava.

A STUDY OF SUPERIOR VENA CAVA OBSTRUCTION SYNDROME.

Project description:Superior vena cava obstruction syndrome was studied in 22 patients with a view to assess the etiological pattern and clinical profile. It was found that 4 patients (18.1%) had benign disease and the remaining 18 (81.9%) patients had malignancy. In 13 patients (59.9%) obstruction occurred due to bronchogenic carinoma. No complications occurred with invasive diagnostic procedures. All heavy smokers (59.9%) were found to have malignancy. Normal lung fields on chest radiography and CT scan with superior vena obstruction syndrome suggested benign disease in 2 cases.

A transudative chylothorax associated with superior vena cava syndrome.

Project description:The chylothorax is a lymphocyte predominant protein-discordant exudative pleural effusions with low lactate dehydrogenase and elevated triglyceride levels. Transudative chylothoraces associated with Superior Cava syndrome (SVC) are an extremely rare clinical entity. In this manuscript, we describe a case of transudative chylothorax due to SVC obstruction secondary to thrombosis of a peripheral inserted central venous catheter, which ultimately resolved after endovascular intervention. In our review of the literature, only five cases of transudative chylothorax associated with SVC syndrome were identified with 60% of cases associated with thrombosis and complications due to catheters in the central venous circulation. Treatment of the underlying cause is key to resolution of the chylothorax. Thoracentesis is an initial intervention for diagnostic and therapeutic purposes. Endovascular intervention is the primary mode of treatment for SVC thrombosis and stenting is preferred for malignant causes, however anticoagulation alone has been reported in the resolution of chylothorax. In patients with recurrent chylothorax despite of relief of SVC obstruction, a medium-chain triglyceride diet and octreotide can be prescribed in order to decrease the chyle flow in the thoracic duct. Surgical ligation of the thoracic duct can be considered if medical management and endovascular treatment fails.

Absent right superior vena cava and persistent left superior vena cava: An incidental finding.

Project description:A patient with Marfan syndrome undergoing Bentall operation was found to have an absent right superior vena cava and persistent left superior vena cava. The dilation of coronary sinus raised the suspicion of persistent left superior vena cava. The diagnosis was confirmed by agitated saline contrast echocardiography and computed tomography of the chest.

Absent right superior vena cava.

Project description:A patient planned to be performed catheter ablation. However, three-dimensional contrast-enhanced chest computed tomography revealed isolated persistent left superior vena cava. We should know such an anatomical abnormality especially when central venous catheter or peripherally inserted central catheter is inserted from right jugular vein or right subclavian vein.
